Maurice Luque, spokesman for San Diego's Fire-Rescue Department,
said the leak in the 10000 block of Carmel Mountain Road was
discovered when someone driving in the area smelled the fumes at
10:10 p.m. Monday.

"There was no problem inside the fitness center," Luque said.
"People were evacuated as a precaution."

A San Diego Gas & Electric Co. crew repaired the break just
before 2 a.m., he said.
